But what pain commands us to do, how we might satisfy this command, and if our experience of pain is inherently linked to suffering are far murkier topics. This paper brings together empirical studies of pain reprocessing during advanced meditation, the rise of allostatic paradigms to account for biological self-regulation, and the philosophy of pain in the classical Sanskrit philosophical tradition of Pratyabhijñā Śaivism to argue that pain is an allostatic imperative to adapt a part of one's body. We theorize two components of an allostatic response, heterostatic and homeostatic, that work in tandem to address pain as an allostatic command. Homeostatic responses are error-corrective in that they seek to protect an organism by returning to a previously stable steady state. Heterostatic responses are anticipatory in that they seek to better prepare an organism to meet future challenges by proactively shifting to a new steady state. We note that an organism's successful adaptation to its environment depends not just on error-correction, but also on anticipatory change. We theorize that a broad range of affect properly accompanies pain. We propose potential directions for empirically developing this model.

Specifically, derealisation describes the experience of detachment from the external world and altered visual perception in which the surroundings look faded, foggy, or dream-like. Whilst some have argued that there may not be genuine perceptual changes in derealization, this proposal is yet to be tested empirically. Thus, we set out to investigate the potential perceptual changes in derealization. In this Registered Report, we conducted two online experiments to reveal the impact of DP/DR symptoms measured <i>via</i> the state version of the Cambridge Depersonalisation Scale (CDS) on how people evaluate (Experiment 1, <i>N</i> = 200, CDS-state mean: 32.43 ± 29.94 SD) and adjust (Experiment 2, <i>N</i> = 125, CDS-state mean: 29.38 ± 30.47 SD) naturalistic scene images with different levels of saturation and contrast. Participants were asked to rate how real the presented images look compared to their everyday experience (in Experiment 1) and to adjust the contrast or saturation level of images to match their everyday visual experience (in Experiment 2). We tested the effect of CDS-state scores on these subjective ratings <i>via</i> model comparison with Bayes Factors. In both experiments, we found strong evidence supporting the null models, suggesting that DP/DR symptoms did not affect realness ratings or vividness adjustments. These results provide empirical support for theories suggesting that self-reported altered vividness experience in derealization does not reflect genuine perceptual changes, instead they signify the (meta-)cognitive interpretation of these experiences.

We examined the electrophysiological brain signals of expert Buddhist monks during two established meditation methods known as Samatha and Vipassana, which employ focused attention and open-monitoring technique. By combining source-space magnetoencephalography with advanced signal processing and machine learning tools, we provide an unprecedented assessment of the role of brain oscillations, complexity, and criticality in meditation. In addition to power spectral density, we computed long-range temporal correlations (LRTC), deviation from criticality coefficient (DCC), Lempel-Ziv complexity, 1/f slope, Higuchi fractal dimension, and spectral entropy. Our findings indicate increased levels of neural signal complexity during both meditation practices compared to the resting state, alongside widespread reductions in gamma-band LRTC and 1/f slope. Importantly, the DCC analysis revealed a separation between Samatha and Vipassana, suggesting that their distinct phenomenological properties are mediated by specific computational characteristics of their dynamic states. Furthermore, in contrast to most previous reports, we observed a decrease in oscillatory gamma power during meditation, a divergence likely due to the correction of the power spectrum by the 1/f slope, which could reduce potential confounds from broadband 1/f activity.

In two experiments, one group of participants reported awareness offline, in a post-test, and another reported it online, in each trial. To test the effect of training, all participants completed two sessions on separate days. When analyzing all trials, we found overall slower reaction times (RTs) in the online group, suggesting a multi-task cost, but no interaction with the priming effect. Notably, this difference was smaller in the second session, implying that the multi-task cost is reduced by training. Critically however, this analysis yielded no convincing evidence for unconscious priming (due to potential threat of regression to the mean). We accordingly analyzed only trials where RTs were fast. Convincing response priming was found, as well as an interaction between priming and session. This suggests that training did increase priming. We also exploratorily tested for individual differences in priming and found between-session consistency mostly for the offline condition. Taken together, our results indicate that although multi-tasking adds noise and prolongs RTs, it does not necessarily diminish unconscious response priming for fast trials, which in turn can be enhanced by training. Costs and benefits of these methodological choices should thus be considered in future studies, as well as targeting only fast responses, where the effects were more compelling.

This claim suggests such beliefs may be attempts to interpret barely perceptible stimuli. The strongest evidence for this comes from Crawley et al. (2002), who found transliminality was associated with responses to subperceptual primes. In the current study, we attempted a high-powered replication of Crawley et al.'s findings that: (i) transliminality predicts identification of subperceptual visual primes, and (ii) this relationship is explained by stimulus sensitivity rather than response bias. Participants completed a transliminality measure and an online card guessing task in two parts. In part one, participants were shown 100 images of playing cards and asked to guess which of five shapes was on the other side of the card. A total of 50 trials contained a subperceptual prime in the form of a target shape, and 50 trials were unprimed. In part two, participants were shown 20 primed and 20 unprimed trials. They were told a prime was sometimes present and asked to report whether they noticed this on each trial. We found strong evidence against an association between transliminality and prime perception in both tasks.

To investigate this, researchers typically compare participants' ability to consciously discriminate a stimulus to their unconscious processing of the same stimulus (e.g. measured via reaction time or brain activity). If participants are not significantly different from chance in the awareness (or \"direct\") measure while nevertheless there is a significant effect in the processing (or \"indirect\") measure, researchers argue that there is no conscious processing of the stimulus, while the stimulus is nevertheless somehow processed, as indicated by the processing measure. In consequence researchers conclude that the stimulus has been processed unconsciously. Using neuroimaging techniques such as functional magnetic resonance imaging (fMRI), researchers then infer which brain regions are involved in unconscious versus conscious processing. However, this methodology is based on a fundamental statistical fallacy that has likely led to an overestimation of the scope of unconscious processing, regarding both its capacity and the brain areas involved. The key problem is that sensitivities in the two measures are never directly compared. Therefore, it is not appropriate to conclude that the processing measure had higher sensitivity than the awareness measure. We reanalyzed the results from 16 fMRI studies directly comparing the sensitivities of both measures in 80 experimental conditions. Our results show that, using this sensitivity comparison method, only eight experimental conditions provide evidence for unconscious processing.

We considered several sources of uncertainty: response-related uncertainty, related to the participants and observed in their response variability, and perceptual or attentional uncertainty related to the sensory stimulation. Our results suggest that adults can reliably estimate the mean and dispersion of their performance and use it together with stimulus-dependent uncertainty to inform their global performance monitoring. In particular, participants adequately report that their performance was worse when uncertainty was higher. However, this capacity decreases when different types of uncertainty increase jointly.
